Giro Ionos Road Helmet

The most beautiful and technologically advanced road cycling helmet Giro has ever made comes fully equipped with ground-breaking ventilation, unparalleled style, and a brand new retention system for an amazing level of comfort, stability, adjustability and weight savings.

In-Mold construction reinforces the area around the vents and ribs, creating a one-piece exoskeleton, which allows the helmet to be lighter, more durable and better ventilated than traditional designs

Quite possibly the best-fitting retention system you've ever experienced, the Roc Loc 5 easily adjusts both fit tension and vertical position with a single hand, plus it's 40% lighter than its popular predecessor, Roc Loc 4
